Some Notes on the Machines

My favorite by far:

Two more I have used:

https://www.calligra.org/flow/

This is a great way:

HPE must be growing a sense of humor. This thing really works well:

This one works very well indeed. It does need a bit more technical intervention:

https://www.bcuninstaller.com

Here are web sites for diagnosing DNS, Internet email, and other issues.

http://mxtoolbox.com

A very good place to test Internet email servers and servers in general exposed to the Internet at large.

http://dnsstuff.com

DNSstuff is excellent for diagnosing DNS issues of all kinds.  Most of its tools require a small subscription fee.

http://whatismyipaddress.com/

whatismyipaddress.com is very good for obtaining geographical and ISP information for an IP address.

https://www.testexchangeconnectivity.com/

is very good for testing Exchange WAN services, e.g., smartphone access, Outlook Anywhere.

For certain tasks, it can be helpful to run CMD as SYSTEM. This can be done with paexec:

paexec -s -i -d cmd.exe

or psexec:

psexec -sid %SYSTEMROOT%\System32\cmd.exe

AnyBurn seems to be possibly the current best light & powerful CD/DVD toolbox item:

www.anyburn.com/download.php

It’s available in 64-bit and 32-bit versions. ImgBurn was go-to for a long time, but it hasn’t had updates since 2013. Quite a few others are gone too. But the old reliable CDBurnerXP is still being kept up to Windows 10 as well:

Test if UDP ports are open to the Internet.

These may come in handy:

Many old friends, e.g. Hiren’s and UBCD4Win, are no longer in development, and do not boot on quite a lot of newer hardware; for a while there was no clear replacement. The only one known to this writer that works well on current made-for-10 hardware, is Medicat:
